Trait RecountSource 

pub trait RecountSource {
    // Required method
    fn recount_patch(
        &self,
        from: &str,
        to: &str,
    ) -> Result<Vec<u8>, EngineError>;
}

Invariant 4’s independent patch source, and nothing else.

A separate trait from DiffSource on purpose. Invariant 4 recounts @@ headers over a patch of the tree the engine built, using a counter that is deliberately not the parser. Sharing an accessor with enumeration would mean one edit to one flag silently moving both sides of the comparison together.

An implementation MUST call git directly and MUST NOT delegate to DiffSource::canonical_patch — note the argv genuinely differs today, and that duplication is the point rather than an oversight.

The return type is Vec<u8> and must stay Vec<u8>: the moment this port hands invariant 4 anything structured, the counter stops being independent.

Required Methods

fn recount_patch(&self, from: &str, to: &str) -> Result<Vec<u8>, EngineError>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
